- Abstract:
- ... In light of global population growth and the increasing food demand in cities, new food production strategies have been developed to promote a more resource-efficient urban agriculture. Greenhouses with hydroponic systems have been proposed as sustainable systems for growing food in urban areas with a better control of plant growth. However, nutrient management in hydroponic agricultural systems i ...

- Abstract:
- ... In Romania, analysis of plant disease samples received from the local landscape industry and homeowners reveals that environmental stresses and nutrition practices are the primary causes of plant failure in the landscape. Chrysanthemum var. is the most important traditional flower crop in Targoviste, Romania. The region is famous for its “Chrysanthemum festival” organised every autumn. The overall ...

- Abstract:
- ... Most organisms engage in beneficial interactions with other species; however, little is known regarding how individuals balance the competing demands of multiple mutualisms. Here we examine three-way interactions among a widespread grass, Schedonorus phoenix, a protective fungal endophyte aboveground, Neotyphodium coenophialum, and nutritional symbionts (arbuscular mycorrhizal fungi) belowground. ...

- Abstract:
- ... Concentrated animal feeding operations (CAFOs) generate large volumes of manure and manure-contaminated wash and runoff water. When applied to land at agronomic rates, CAFO wastewater has the potential to be a valuable fertilizer and soil amendment that can improve the physical condition of the soil for plant growth and reduce the demand for high quality water resources. However, excess amounts of ...

The variability in soil test recommendations for nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) was measured, along transects across three fields in the South Peace River region of Alberta. Depending on the field and intended crop, site-specific fertilizer a ...

Among them, SWE and humic acid (HA) are widely used in various biostimulant product formulations. These compounds have been reported to contain phytohormones and osmoprotectants such as cytokinins, auxins, poly ...

In this study, the effects of nutrients on three dominant Australian mangrove species (Avicennia marina, Ceriops tagal and Rhizophora stylosa) were examined in a sand culture experiment. A factorial design with three levels each of N, P and K, and two levels of NaCl, was used. Nutrient ...

Two popular concepts of soil fertilization, basic cation saturation ratio (BCSR) and sufficiency level of available nutrients (SLAN), were tested on a calcareous soil (Aeric haplaquept) during 1995-1996 at the Bangladesh Rice Research Institute (BRRI) Regional Station Rajshahi using wheat as a test crop. According to BCSR concept the soil was deficient in potassium (K) and according to SLAN concep ...

The interaction of nutrients with K may be in the soil or in plant. Potassium modifies ammonium ...
